Area of Science:

Ophthalmology
Cardiology
Medical Imaging

Background:

The ocular fundus offers a unique view of the human vascular system.
Evidence suggests links between ocular fundus vascular measures and cardiovascular diseases.
Accurate and repeatable measurement methods are needed to statistically validate these links.

Purpose of the Study:

To present a system assisting physicians in measuring vascular characteristics in non-mydriatic ocular fundus images.
To facilitate the signaling and storage of data related to vascular deterioration and caliber.
To enable precise and repeatable data acquisition for statistical analysis.

Main Methods:

Development of a system with a graphical user interface (GUI).
GUI guides practitioners in marking visible anatomical features.
